Definitions
- the present invention relates to phacoemulsification surgery and more particularly to a device that better regulates infusion pressure.
- the human eye functions to provide vision by transmitting light through a clear outer portion called the cornea, and focusing the image by way of a crystalline lens onto a retina.
- the quality of the focused image depends on many factors including the size and shape of the eye, and the transparency of the cornea and the lens.
- age or disease causes the lens to become less transparent, vision deteriorates because of the diminished light which can be transmitted to the retina.
- This deficiency in the lens of the eye is medically known as a cataract.
- An accepted treatment for this condition is surgical removal of the lens and replacement of the lens function by an artificial intraocular lens (IOL).
- IOL intraocular lens
- a typical surgical hand piece suitable for phacoemulsification procedures consists of an ultrasonically driven phacoemulsification hand piece, an attached hollow cutting needle surrounded by an irrigating sleeve, and an electronic control console.
- the hand piece assembly is attached to the control console by an electric cable and flexible tubing. Through the electric cable, the console varies the power level transmitted by the hand piece to the attached cutting needle.
- the flexible tubing supplies irrigation fluid to the surgical site and draws aspiration fluid from the eye through the hand piece assembly.
- the operative part in a typical hand piece is a centrally located, hollow resonating bar or horn directly attached to a set of piezoelectric crystals.
- the crystals supply the required ultrasonic vibration needed to drive both the horn and the attached cutting needle during phacoemulsification, and are controlled by the console.
- the crystal/horn assembly is suspended within the hollow body or shell of the hand piece by flexible mountings.
- the hand piece body terminates in a reduced diameter portion or nosecone at the body's distal end.
- the nosecone is externally threaded to accept the hollow irrigation sleeve, which surrounds most of the length of the cutting needle.
- the horn bore is internally threaded at its distal end to receive the external threads of the cutting tip.
- the irrigation sleeve also has an internally threaded bore that is screwed onto the external threads of the nosecone.
- the cutting needle is adjusted so that its tip projects only a predetermined amount past the open end of the irrigating
- the tip of the cutting needle and the end of the irrigation sleeve are inserted into the anterior capsule of the eye through a small incision in the outer tissue of the eye.
- the surgeon brings the tip of the cutting needle into contact with the lens of the eye, so that the vibrating tip fragments the lens.
- the resulting fragments are aspirated out of the eye through the interior bore of the cutting needle, along with irrigation solution provided to the eye during the procedure, and into a waste reservoir.
- irrigating fluid is pumped into the eye, passing between the irrigation sleeve and the cutting needle and exiting into the eye at the tip of the irrigation sleeve and/or from one or more ports, or openings, cut into the irrigation sleeve near its end.
- This irrigating fluid is critical, as it prevents the collapse of the eye during the removal of the emulsified lens.
- the irrigating fluid also protects the eye tissues from the heat generated by the vibrating of the ultrasonic cutting needle. Furthermore, the irrigating fluid suspends the fragments of the emulsified lens for aspiration from the eye.
- a common phenomena during a phacoemulsification procedure arises from the varying flow rates that occur throughout the surgical procedure. Varying flow rates result in varying pressure losses in the irrigation fluid path from the irrigation fluid supply to the eye, thus causing changes in pressure in the anterior chamber (also referred to as Intra-Ocular Pressure or IOP.) Higher flow rates result in greater pressure losses and lower IOP. As IOP lowers, the operating space within the eye diminishes.
- the present invention is a pressurized infusion device comprising a flexible band having first and second ends, a curved base, and a bag containing fluid.
- the bag is located between the flexible band and curved base.
- the second end of the flexible band is coupled to a shaft.
- a motor is also coupled to the shaft. The motor is actuated to turn the shaft and produce tension in the band thereby changing the fluid pressure in the bag.
- the present invention is a pressurized infusion system for an ophthalmic surgical machine.
- the pressurized infusion system comprises a flexible band having first and second ends; a curved base; a bag containing irrigating fluid, the bag located between the flexible band and curved base; an irrigation line coupled to the bag; a pressure sensor for reading pressure in the irrigation line; a motor coupled to a shaft, the second end of the band coupled to the shaft; and a controller, the controller receiving an input from the irrigation pressure sensor to control the motor.
- the motor is actuated to turn the shaft, tension is produced in the band to change pressure in the bag.

- FIG. 1 is a diagram of the components in the fluid path of a phacoemulsification system including a pressurized irrigation squeeze band according to the principles of the present invention.
- FIG. 1 depicts the fluid path through the eye 145 during cataract surgery.
- the components include a motor 105 , a band 110 , a bag 115 , a curved base 120 , a frame 125 , an irrigation pressure sensor 130 , an irrigation valve 135 , an irrigation line 140 , a hand piece 150 , an aspiration line 155 , an aspiration pressure sensor 160 , a vent valve 165 , a pump 170 , a reservoir 175 and a drain bag 180 .
- the irrigation line 140 provides irrigation fluid to the eye 145 during cataract surgery.
- the aspiration line 155 removes fluid and emulsified lens particles from the eye during cataract surgery.
- a bag 115 contains irrigation fluid for use during cataract surgery.
- the bag 115 is located between band 110 and curved base 120 .
- Curved base 120 is mounted to frame 125 .
- a motor 105 has a shaft (not shown) that is attached to one end of band 110 .
- the other end of band 110 is fixed to the curved base 120 or the frame 125 .
- the bag 115 can be squeezed between band 110 and curved base 120 .
- motor 105 is actuated so that the shaft (not shown) to which motor 105 is coupled turns, the band 110 is wound around the shaft (not shown) thereby squeezing bag 110 against curved base 120 . This acts to squeeze irrigation fluid out of bag 110 . This is shown more clearly in subsequent drawings.
- An irrigation pressure sensor 130 measures the pressure of the irrigation fluid in irrigation line 140 .
- An optional irrigation valve 135 is also provided for on/off control of irrigation.
- Irrigation pressure sensor 130 is implemented by any of a number of commercially available fluid pressure sensors. Irrigation pressure sensor 130 provides pressure information to a controller (not shown) that operates motor 105 . The operation of motor 105 (and attached band 110 ) controls the pressure of the irrigation fluid exiting bag 115 .
- Motor 105 can be a DC motor, stepper motor, or other type of motor which can be precisely controlled. In other embodiments of the present invention, motor 105 can be any type of mechanism that is capable of exerting a force on band 110 .
- a hand piece 150 is placed in the eye 145 during a phacoemulsification procedure.
- the hand piece 150 has a hollow needle (not shown) that is ultrasonically vibrated in the eye to break up the diseased lens.
- a sleeve located around the needle provides irrigation fluid from irrigation line 140 .
- the irrigation fluid passes through the space between the outside of the needle and the inside of the sleeve. Fluid and lens particles are aspirated through the hollow needle.
- the interior passage of the hollow needle is fluidly coupled to aspiration line 155 .
- Pump 170 draws the aspirated fluid from the eye 145 .
- An aspiration pressure sensor 160 measures the pressure in the aspiration line.
- An optional vent valve can be used to vent the vacuum created by pump 170 .
- the aspirated fluid passes through reservoir 175 and into drain bag 180 .
- the tip of the needle can become occluded with a lens particle. This creates a condition that is called an occlusion.
- an occlusion less fluid is generally aspirated from the eye.
- the vacuum pressure in aspiration line 155 builds up as a result of the occlusion.
- aspiration pressure sensor 160 reads the increased vacuum that builds up in aspiration line 155 .
- the occlusion breaks (that is when the lens particle that causes the occlusion is broken up by the ultrasonic needle)
- a surge occurs.
- the built up vacuum in aspiration line 155 creates a sudden demand for fluid from the eye resulting in a rapid lowering of IOP and shallowing of the operating space within the eye. This can lead to a dangerous situation in which various structures of the eye can be damaged.
- the squeeze band device of the present invention is capable of responding to this surge effect by increasing the irrigation pressure in irrigation line 140 .
- band 110 is tightened in response to the decrease in irrigation pressure sensed by irrigation pressure sensor 130 . In this manner, the pressure and resulting operating space in eye 145 can be maintained at a relatively constant value.
- irrigation pressure may increase as the fluid aspirated from the eye decreases.
- An increase in irrigation fluid pressure detected by irrigation pressure sensor 130 can be used to control motor 105 (and attached band 110 ) to regulate the pressure in eye 145 —that is to keep the pressure in eye 145 within acceptable bounds.
- FIG. 2 is an end view of a pressurized irrigation squeeze band apparatus according to the principles of the present invention.
- bag 115 is held between band 110 and curved base 120 .
- Shaft 210 is attached to motor 105 (not shown). Motor 105 turns shaft 210 to tighten (or loosen, as the case may be) band 110 .
- motor 105 is a DC motor or stepper motor
- shaft 210 can be turned precisely to apply a known amount of force on bag 115 .
- the force placed on bag 115 by band 110 is proportional to the pressure of the irrigation fluid in the irrigation line to which bag 115 is connected.
- the tension of band 110 forces the bag 115 to conform to the convex curve shape of the curved base 120 .
- There is a linear relationship between pressure in bag 115 and the tension in band 110 approximated by the hoop stress formula: ⁇ h Pr/t
- ⁇ h hoop stress (in this case, band stress from tension on the band 110 )
- P internal pressure (in this case, pressure in the bag 115 )
- t thickness of the hoop (in this case, the thickness of band 110 )
- r the inside radius of the circle (in this case, the radius of curved base 120 )
- Band 110 can be made of a flexible but non-stretching material such as a thin flexible metal or plastic sheet, woven material, or other suitable material.
- band 110 is made of a 0.010 inch thick UHMW polyethylene sheet.
- FIG. 3 is a side view of a pressurized irrigation squeeze band apparatus according to the principles of the present invention.
- bag 115 is held between band 110 and curved base 120 .
- Curved base 120 is mounted to frame 125 .
- Shaft 210 is coupled to motor 105 .
- band 110 is tightened (or loosened depending on the direction that shaft 210 is turned).
- the pressure in the eye 145 can be maintained within acceptable bounds.
- FIG. 4 is a block diagram of a pressurized irrigation squeeze band apparatus according to the principles of the present invention.
- a controller 410 receives an input from irrigation pressure sensor 130 and controls the operation of motor 105 . In this manner, controller 410 controls motor 105 to adjust irrigation pressure.
- Controller 410 is typically an integrated circuit with power, input, and output pins capable of performing logic functions.
- controller 410 is a targeted device controller. In such a case, controller 410 performs specific control functions targeted to a specific device or component, such as a motor.
- motor controller has the basic functionality to control motor.
- controller 410 is a microprocessor.
- controller 410 is programmable so that it can function to control more than one component of the device.
- controller 410 is not a programmable microprocessor, but instead is a special purpose controller configured to control different components that perform different functions. While depicted as one component in FIG. 4 , controller 410 may be implemented by many different components or integrated circuits.
- FIG. 5 is a block diagram of control system for a pressurized irrigation squeeze band apparatus according to the principles of the present invention.
- an input 350 represents the desired pressure.
- controller 410 is a PID controller that controls the operation of motor 105 .
- the irrigation pressure sensor 130 provides an input to controller 410 .
- Controller 410 tracks the desired pressure (input 350 ) by controlling motor 105 . For example, if the irrigation pressure is too low (lower than the desired pressure), controller 410 directs motor 105 to tighten band 110 thereby increasing the pressure in bag 115 (and the irrigation line to which bag 115 is coupled). If the irrigation pressure is too high (higher than the desired pressure), controller 410 directs motor 105 to loosen band 110 thereby decreasing the pressure in bag 115 (and the irrigation line to which bag 115 is coupled).
- FIG. 6 is a perspective view of a pressurized irrigation squeeze band apparatus according to the principles of the present invention.
- bag 115 is held between band 110 and curved base 120 .
- Curved base 120 is mounted to frame 125 .
- Shaft 210 is coupled to motor 105 .
- FIG. 7 is a side view of a pressurized irrigation squeeze band apparatus according to the principles of the present invention.
- motor 105 and curved base 120 are as described above.
- Clutch 710 is coupled to motor 105 .
- Spring 720 is coupled to shaft 210 .
- Clutch 710 engages or disengages the motor 105 and shaft 210 .
- clutch 710 provides a safety feature allowing for the shaft 210 to be disengaged from motor 105 if necessary.
- Spring 720 provides a constant torque on shaft 210 if motor 105 disengages from shaft 210 . In this manner, if clutch 710 disengages motor 105 from shaft 210 , then spring 720 provides a constant torque on shaft 210 to maintain a constant minimum pressure in the irrigation line (and the eye).
- the irrigation squeeze band device of the present invention provides for precise control of irrigation pressure (and pressure in the eye) during cataract surgery.
- Prior attempts at a squeeze bag type device included using two opposing plates between which the bag is placed. The plates are moved together to increase pressure in the bag. It was discovered, however, that the bag was susceptible to movement while located in between the plates. This movement caused the control of the pressure to be slower than in the squeeze band device of the present invention.
- band 110 holds bag 115 securely against curved base 120 . This allows for quicker and more precise control of pressure.
- the surface contact area of the bag and rigid plates would vary significantly at different bag fill levels. As a result, at different bag fill levels, significantly different forces would be required to produce the same pressure, thus making consistent device control more challenging.
- the present invention provides significant benefit in minimizing contact surface area variation throughout bag volume depletion.
- the band conforms to the bag surface on one side, keeping the area nearly constant. While the base to bag contact area somewhat varies, the variations are not as significant as in case of the flat plates.
- the present invention provides a pressurized infusion system for phacoemulsification surgery.
- the present invention provides an irrigation squeeze band device that more precisely controls fluid pressure.
- the present invention is illustrated herein by example, and various modifications may be made by a person of ordinary skill in the art.
